This thread kind of sunk away, but I would like to bring it up again.Currently I'm swapping between a regular fretted 12-tet guitar, a fretless where I use 31-tet and recently I'm using 53-tet when playing around with Indian (just-tuned) scales.

It would be great if I could start different sessions in Non-Session-Manager for each tuning / TET.

Further the 53-TET uses a relative nomenclature (a derivate of Do-Re-Mi), which is ideal for Indian music.So being able to set the frequency for "Do" would be great.

I don't have the slightest idea how hard this is to do, but just wondering...

About setting the frequenty. You don't have to change much I think only to widen the bandwidth of the frequenty (somewhere between 225 and 450).So when I want to use a C as root, the command line would be: guitarix -t 53 -f 440But when I want to use G as root 440*3/4 = 330 Hz --> guitarix -t 53 -f 330and so on.
